Surgical Collection Liner With Integrated Rigid Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical collection liners have limited capacity, are cumbersome to handle when full, and require complex assembly and disassembly, making them difficult to manage and increasing the risk of errors during use.
Innovation Solution
A collection liner with a flexible plastic bag portion and a rigid handle, featuring secure inlets for vacuum and fluid collection, a hydrophobic filter for leak prevention, and an ancillary handle for easier lifting, along with a modular apparatus for efficient fluid management and solidifying agent distribution, which includes a movable cart and internal vacuum source for improved workflow and error prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the collection liner is designed with large volume capacity, then the fluid collection capability is improved, but the weight and handling difficulty increase
Solution Approach 1:
The collection liner is divided into two functional parts: a flexible bag portion for fluid collection and a rigid handle for manipulation. This segmentation allows the bag to expand to large volumes while the handle maintains a manageable size and weight for easy handling.
Solution Approach 2:
The rigid handle acts as an intermediary between the user and the large-volume bag portion. It provides a secure grip point and structural support, enabling users to lift and maneuver heavy, fluid-filled containers without directly handling the entire mass.
2Adaptability or versatility
If the collection liner comprises multiple tubes and components, then the functionality is improved, but the assembly complexity increases
Solution Approach 1:
Multiple functional components (inlets, outlets, valves, and connections) are integrated into a unified structure where the rigid handle houses and organizes all necessary ports and mechanisms. This merging reduces the number of separate parts that need to be assembled while maintaining full functionality.
Solution Approach 2:
The rigid handle serves multiple functions simultaneously: it provides structural support, houses all inlet and outlet connections, incorporates valves for fluid control, and offers a grip for handling. This multi-functionality eliminates the need for separate components for each function.
3Reliability
If the inlet connections are made secure to prevent leakage, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The connection system incorporates self-sealing mechanisms and automatic valve operations that prevent leakage without requiring complex external control systems. The design ensures that connections secure themselves through pressure differentials and integrated sealing features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the ease of handling and managing large volumes of fluid, reduces material and storage needs, and minimizes errors through secure assembly and efficient fluid management, while ensuring effective suction and solidifying agent distribution.
Implementation Method 1
The filter prevents fluid to advance into the vacuum tubing of the apparatus. The hydrophobic filter is made of a material which swells if the liquid meets the filter, thus blocking the flow.
Implementation Method 2
The thin plastic tube is open only when the pressure inside the tube is higher than around it.
Implementation Method 3
The inlet for the vacuum has a lateral branch which is a channel for transmitting negative pressure outside the collection liner.
Data Source
AI summary
A collection liner for a medical or a surgical operation is disclosed which includes a closed bag portion and inlets opening into the bag portion. The collection liner can include a handle which includes at least one of the inlets inside the handle.
